Close binary and other variable stars in the solar-age galactic open cluster M67
Yakut, Kadri; Zima, W.; Kalomeni, Belinda; Van Winckel, H.; Wealkens, C.; De Cat, P.; Bauwens, E.; Vučković, M.; Saesen, S.; Le Guillou, L.; Parmaksızoğlu, M.; Uluç, K.; Khamitov, I.; Raskin, G.; Aerts, C. (EDP Sciences, 2009-08)We present multi-colour time-series CCD photometry of the solar-age galactic open cluster M67 (NGC 2682). About 3600 frames spread over 28 nights were obtained with the 1.5 m Russian-Turkish and 1.2 m Mercator telescopes. ... -
Photometric multi-site campaign on massive B stars in the open cluster chi Persei (NGC 884)
Saesen, S.; Pigulski, A.; Carrier, F.; De Ridder, J.; Aerts, C.; Handler, G.; Drummond, R. (IOP PUBLISHING LTD, 2008)In 2005 a photometric observation campaign started on the open cluster chi Persei, involving 13 telescopes spread over the whole northern hemisphere. After two years we gathered almost 1200 hours of data. We present here ... -
Photometric multi-site campaign on the open cluster NGC 884 I. Detection of the variable stars
Saesen, S.; Carrier, F.; Pigulski, A.; Aerts, C.; Handler, G.; Narwid, A.; Debosscher, J. (EDP SCIENCES S A, 2010)Context. Recent progress in the seismic interpretation of field beta Cep stars has resulted in improvements of the physics in the stellar structure and evolution models of massive stars. Further asteroseismic constraints ... -

Towards ensemble asteroseismology of the young open clusters chi Persei and NGC 6910
Saesen, S.; Pigulski, A.; Carrier, F.; Michalska, G.; Aerts, C.; De Ridder, J.; Zima, W. (WILEY-V C H VERLAG GMBH, 2010)As a result of the variability survey in chi Persei and NGC 6910, the number of beta Cep stars that are members of these two open clusters is increased to twenty stars, nine in NGC 6910 and eleven in chi Persei. We compare ...
